Two cases of aberrant right subclavian artery and right vertebral artery that originated from the right common carotid artery.

Park JK, Kim SH, Kim BS, Choi G - Korean J Radiol (2008)

Bottom Line: We present here two patients that had an aberrant right subclavian artery and an anomalous origin of the right vertebral artery from the right common carotid artery.We review the previous literature and discuss herein the embryologic mechanism and clinical implications of this variation.

Aberrant right subclavian artery with right vertebral artery originating from right common carotid artery.A. Enhanced oblique coronal multiplanar reconstruction CT image shows aberrant right subclavian artery (arrow) originating from aortic arch distal to left subclavian artery.B. Oblique sagittal maximum intensity projection image shows right vertebral artery originating from right common carotid artery at inferior border of right thyroid gland, and note aberrant entrance to C5 transverse foramen.C. Enhanced axial CT image reveal close spatial relation between right vertebral artery originating from right common carotid artery (arrow) and right thyroid gland.

Figure 1: Aberrant right subclavian artery with right vertebral artery originating from right common carotid artery.A. Enhanced oblique coronal multiplanar reconstruction CT image shows aberrant right subclavian artery (arrow) originating from aortic arch distal to left subclavian artery.B. Oblique sagittal maximum intensity projection image shows right vertebral artery originating from right common carotid artery at inferior border of right thyroid gland, and note aberrant entrance to C5 transverse foramen.C. Enhanced axial CT image reveal close spatial relation between right vertebral artery originating from right common carotid artery (arrow) and right thyroid gland.

Mentions: A 30-year-old male was admitted to our hospital due to a midline anterior neck mass. On the enhanced CT images, the mass was located at the infrahyoid midline neck and it showed the imaging features of a thyroglossal duct cyst. The enhanced oblique coronal multiplanar reconstruction CT images revealed a variation of the aortic arch as an aberrant right subclavian artery that was distal to the left subclavian artery (Fig. 1A). The right vertebral artery had its origin from the right common carotid artery at the inferior border of the right thyroid gland, and it had an aberrant entrance to the C5 transverse foramen (Fig. 1B). The prevertebral segment of the right vertebral artery was located in the retro-thyroid area and very close to the thyroid gland (Fig. 1C).
